The term “dian” refers to an ancient structure used for storing books. The Imperial Archives is entirely built from carved stone. The main hall has no beams or columns, and the floor features a 1.42-meter-high stone platform on which more than 150 camphorwood cabinets covered in copper and engraved with dragons are arranged. These are called “golden cabinets.” The overall architecture and storage design of the Imperial Archives are exquisitely crafted and fully functional, featuring fireproofing, moisture resistance, mold prevention, and insect protection—ensuring that precious texts remain undamaged and making it highly suitable for the preservation of archival documents.
